It reminds of Luca Cambiaso the great mannerist painter, who would constantly use block forms mostly cubes to represent the different planes of the object he would draw, clarifying their orientation and bulk. This he would do to draw the entire human fgure. face, torso, arms , legs, fingers , the nose, the ankle..everything using cubes. its amazing how clear the various forms and parts of the body becomes when one analyse it using this approach. It can be done without loosing the complexity.yet with clarity.
